How do parallelograms and trapezoids differ?
parallelograms have two sets of parallel lines trapezoids do not
What does all parallelograms have in common?
They all have parallel lines.
Do parallelograms have 2 sets of parallel lines?
Yes they do.
If there are 6 horizontal parallel and 7 vertical parallel lines then how many parallelograms we can get?
Infinite; you could go into the decimal forever.
Does a quadrilateral have parallel lines?
not neccessarily. it can have parallel lines, but it doesn't have to. a kite for example, has no parallel lines, but it is a quad. but it can, such as rhombuses, squares, rectangles, parallelograms, and trapezoids
Why are trapezoids not parrelegrams?
Parallelograms have two sets of parallel lines. Trapezoids only have one pair of parallel lines.
Are all parallelograms and rectangles the same?
No. Rectangles are parallelograms with all right angles, while parallelograms just have 2 sets of parallel lines.
What shapes are quadrilateral but not parallelogram?
a square is not a parallelogram the dude who said is a retard. squares are parallelograms becuz parallelograms has to hve 2 sets of parallel lines, no more, no less. a square has 2 sets of parallel lines.
How many parallelograms are formed when a set of 5 parallel lines intersect a set of 4 parallel lines?
This one is much more straightforward. There are 5C2 = 10 ways to choose two parallel lines from the set of five. There are 4C2 = 6 ways to choose two parallelograms from a set of four. Any parallelogram is uniquely determined by one pair of lines from the five, and one pair of lines from the four. Thus, the number of possible parallelograms is(5C2)*(4C2) = (10)*(6) = 60
How many parallelograms can be formed when a set of 5 parallel linesintersect 4 parallel line?
Select two parallel lines out of 5: 5*4*3/(2*1) = 30 ways Select two parallel lines out of 4: 4*3*2/(2*1) = 12 ways Combine the above 2: 30*12 = 360 parallelograms.
What are the shapes that have at least one pair of parallel lines?
All i know is a Trapezium parallelograms
What figure has parallel diagonals?
Parallelograms have parallel diagonals (these include squares, rectangles, rhombi, an trapezoids). Parallel lines are lines with the same slope that could carry on infinitely without intersecting. A parallelogram can have 1 or 2 sets of parallel lines.
